' Application filed January 17,1968. Serial No. 411,297.

' To all whom it may concern 7 of Allegheny and State of Be it known that We, \VILLIAM J PATTER- soN, a resident of Springdale, in the county Pennsylvania,

and LBRECHT B. NEUMAINA', a resident of Chicago, in the county 'of- Cook and State of Illinois, have inventeda new anduseful Improvement in Casting Plants; and we do hereby clear, and exact description thereof.

Our invention relates to a casting plant. Our invention is more especially applicable to a pig metal casting plant in which-the molten metal as it is brought from the blast furnace in ladles is poured into an endless chain of molds at one end of said chain and the metal is solidified in said molds, so that when the molds arrive at the outer end of the chain the pigs are in condition-to drop from the'molds as the molds are overturned and drop into a car stationed at that end of the chain to receive'the same. In such form of casting apparatus it is-very desirable to arrange for the pouring of the metal from the ladles into the pouring basin so that there will be very little drop in the metal from the ladleto said basin, thereby claimed.

portion thereof; .Fig.- 3 is a plan View; and

preventing the splashing of the molten. metal.- It is also very desirable to have the tracks upon which the ladle cars travel as Well as the tracks on which the cars travel that receive the molded pigs all on the same level; which greatly simplifies the constructhe pouring spouts will bein close proximity to the reservoir or runner from which the molds are supplied, and to providefor the arrangements of the tracks on the same level for the purposes above set forth.

To these ends our invention comprises the novel features hereinafter set forth and Referring to the drawings Figure 1 is a side elevation of our improved casting plant Fig. 2 is an enlarged side elevation of a 'ig. 4 is an enlarged end view of the sup v port and cradle.

In the drawings thenumeral 2 designates declare the following to be a full,

the frame work of a suitable casting house, on the floor 3 of which are arranged the tracks 4: upon which the ladle cars 5 are adapted to travel. These cars 5 carry the ordinary ladles 6 which are removable therefrom said ladles being provided with the main trunnions 7 and the supplemental trunnions 8.

' A frame work 9 is erected to support he pig metal casting apparatus which comprises the sprockets 10 and 11 around which passes the endless chain or mold carrier 12. The molds are secured to this endless car rier 12 and as such a carrier together with the molds are so well known it has not been deemed necessary to illustrate the same in detail. At the upper or outer end of the frame 9 is the chute 13 which delivers the pigs as they are discharged from the molds into the car 14: traveling on the track 15, which is on the same level, or substantially the same levelfas the tracks 4 upon which the ladle cars 5 travel.

Adjacent to the inner end of. the mold I carrier 12 is the stand or support 16 adapted tosupport the cradle or swinging frame 17. This cradle 17 has the trunnions 18 which engage the bearings 1.9 in the stand 16, whereby said cradle is adapted to swing from said trunnions. The lower end of the cradle 17 rests upon the stool 20. The lower end of the cradle is provided with the ring 21. Recesses 22 are formed in the cradle 17, saidrecesses being provided. with the inclined faces 23. A stop 24 is provided to control the inward movement of the lower cradle, as fully hereinafter set forth.

16 is the basin 25 into which the molten having the outlets 26 at each side thereof through which the molten metal flows into the molds of the mold carrier. It is usual to arrange two parallel chains of molds so that the basin 25 is arranged between them in such a manner that the metal will flow from the openings 26 to each side thereof to supply the molds of the mold carriers.

crane 28 adapted to swing in the ordinary manner. At the outer end of the jib 29 is the pulley 30, and at the lower end of said jib on the main mast of the crane is the pulley 31. At the top of the main mast of end of the ladle when seated within the.

l Located adjacent to the stand or support metal is poured from the ladle, said basin Erected upon the platform 27 is the jib' forth.

the crane is the pulley 82. The main Inast of the crane is further provided with the" pulley v33. Located within suitable distance of the crane is the motor 34. A gear on the 1notor shaft meshes with the gear wheel 36 on the counter-shalt 37. A gear wheel 88 on the shaft meshes with the gear wheel 39 on the worm shaft 40. This worm shaft 40 meshes with the worm wheel'41 on the shaft 42. On this shaft 42 is the drum 43. A second drum 44 has the clutch 45 provided for throwing said drum into andout of engagement with the shaft 42; Diagonally arranged pulleys 46 are arranged above the drum 44 in suitable bearings. A pulley 47 is arranged in line with the pulley 32 overhead and above the drum 43.

A chain 48 is connected to the blockpulley 49 around which passes the cable 50,-said cable passing over the pulley 30, thence down and around the pulley 31 and up and over the pulley 32, thence across to the pulley 47 and downwardly and around the drum-43. is apparent that by winding or unwinding the cable on the druni 43 the chain 48 is raised and lowered, as fully hereinafter set The rope or cable. 51 for swinging the crane passes around the pulley 33 and thence over the pulley 46 and downwardly and around the drum' 44.

The shaft 42 .may be rovided with the brake wheel 52 fitted wit -a -suitable brake band 53 of, ordinary construction, whereby the speed of. the controlled. I I

. A suitable travelin crane 55 is arranged to travel upon suitab e supports 56 within 6 from the blast furnaces along the tracks The main trolley of, the overhead crane is brought into position with its hooks 59 engaging the central trunnions 7 of the ladle, whereupon the ladle is lifted fromthe car 5- and deposited in the cradle 17.

The supplemental trunnions 8 fit within the recess 22 of the cradle and the'inclined faces insure the guiding of the ladles into position properly within the cradle. W hen the ladle has been deposited in the cradle in this manner the hooks 59 of the main trolley 57 are released from the central tru'nnions 7 and the trolley withdraws shaft .42 .may' be properly to one side, whereupon theswinging crane 28 which has been swungout of position is operated to bring its jib around in position for the chain 48 to be secured by the hook engagement with the shaft 42 by the clutch 45. By the winding of the cable 51 on the drum 44 the crane'is swung around into the position shown in Fig. 1. The clutch 45 is then thrown out of engagement with the drum 44 and the drum 43 is then brought into engagement with said shaft, whereupon the cable 50 is loweredv to bring the chain 48 down into position .to engage the ring 21 of the cradle 17 Power is then applied to rotate the drum 42 in the opposite direction, whereupon the cable 50 is wound on said'druni so as to lift the chain 48 and with'it the cradle 17. The cradle 17 being trunnioned in .the stand 16, the ladlesupported bysaid cradle is'lifted and tilted in the manner indicated in Fig. 1 so as to pour the metal therefrom into the receptacle or reservoir 25. The pouring spout of the ladle is in very close proxinnty to the reservoir so that as'the ladle is tilted gradually the metal flows from the ladle into the reservoir without splashing. The pouring con- 'tinuesby. the gradual tilting. of the'cradle .until ally the metal has been poured from the ladle into the reservoir 25. The metal passes from the reservoir 25 through the dicated in Fig. 1 whereupon the-chain 48' releasedand the crane 28 swung out of the way. The main trolley 57 is then.

brought into position to have its hooks 59 engage the central trunnions 7 of the ladle whereupon said ladle is lifted from the cradle 17 and carried over to the support- 61, whereupon the auxiliary trolley.58 is brought over in position to have its book 60 engage the ring 62 in the bottom of the ladle. By operating the-cables of the auxiliary trolley in the proper manner. the ladle is brought into a horizontal position,'whereupon the ladle is lowered onto the support 61. The ladle isthen in position to have the scale removed therefrom. After the scale has been removedfrom the ladle it is again lifted by the crane 56 and deposited on one ofthe cars to be taken back to the furnace to recelvc a fresh charge of molten 100 openings 26into the molds and is conveyed to the'outer end of the conveyer where the; "pigs which, have been solidified, are d snage of the plant is greatly increased. By-

I having the tracks for the ladle cars as well as the tracks for the pig metal cars on subnecessity of running the ladle cars in on stantially the same level the shifting may all be done on the same level while the tracks at a higher level is dispensed with. hat we claim is:

1. In a castin plant, the combination of an endless traveing mold-carrier, tracks at opposite ends of said mold-carrier, ladlecars traveling on the tracks at inner end of said carrier, cars to receive the molded metal on track at outer end of said moldcarrier, saidtracks being on the same or substantially on the same level, and means for lifting the ladles from said cars' and pouring the metal into the molds of said mold-carrier.
